Canadian building technology firm Renewabuild Field to Form Ltd. announced its first official U.S. licensing agreement this month. The agreement, signed with newly formed Renewabuild Great Plains, Inc., greenlights a planned manufacturing facility in Rock Valley, Iowa, to produce an interlocking load-bearing hemp-lime wall system.
